METAL SHEET-FILING.

Specication of Letters Patent.

Patented March 26, 1907.

Application filed October 18,1905. Serial No, 283,207.

To all whom, t Wl/ty concern:

Be it known that I, J ULIUs R. WEMLINGER, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in MetalSheetPiling, of which the following is a specication.

My invention relates to metal sheet-piling, and has for its object toprovide an improved form of interlocking metal piling particularlyadapted for. use in situations where water-tightness is paramount-as,for instance, when the piling is used in coifer-dams, core-walls ofdams, embankments, jetties, and the like to prevent seepage orpercolation of underground Water. Very often in such cases the pilingmay be made very light, because the material to be penetrated is soft orloosely packed. v j

The metal piling herein described is especially well suited to thisimportant applica tion of metal sheet-piling, because in very lightsections it possesses all the requirements of strength and penetration,while the arrangement of the details is such that absoluteimpermeability may be obtained.

Referring now to the drawing, Figure 1 is a transverse sectional view ofone unit of my new metal sheet-piling. Fig. 2 is a transverse sectionalview of two units joined together. Fig. 3 is an elevation of part of theunits shown in Fig. 2.

Each unitfas shown, comprises a web 1, sides 2, and locking edges 3.These are preferably formed by curving the margin of each side 2 into acylindrical extension, the object being to provide elastic locking edgesfor the purpose hereinafter described. The web 1 is arranged withlocking-'splices formed of a stationary portion 1, secured to said webby rivets 7 and having resilient edges or flanges 5, which providespaces 6 for receiving and locking the edges 3 ofthe contiguous units asthe piling is driven in the usual way. The edges 3 are of dimensionsslightly larger than the width of the spaces 6, as shown by dotted linesat the right-hand side of Fig. 2, so that when the piling is driventhere exists a strong pressure between the locking edges 3, the iianges7, and the web 1, which makes the wall of sheet-piling absolutelywater-tight. The edges 3 are easily introduced into the spaces 6 bysimply flattening the said edges at the leading end of the unit, whichmay be done equally Well in the shop or in the field,

as will be readily understood. The locking edges-3 and the iianges 5 areboth resilient or elastic; but, if preferred, the iianges 5 of thesplices may be made rigid and the locking edges 3 supplied with all therequired elasticity, vor vice versa.

What I claim as new, and desire to secure by Letters Patent, is

l. In metal sl1eet-piling,'units of trough shape having resi-lientcylindrical edges.

2. In metal sheet-piling, units of trough shape having curved edges andresilient means for locking the said units together.

3. In metal sheet-piling, units of trough shape having resilientcylindrical'edges and means for locking the said units together.

4. In metal sheet-piling, units of trough shape having compressibleedges and means Jfor joining the said units together.

5. In metal sheet-piling, the combination of units having compressibleedges and elastic locking-splices for joining the said units together.

6. In metal sheet-piling, the combination of units each having a web andtwo sides, both said. sides having resilient curved locking edges.

7 In metal sheet-piling, the combination of units each having a web andsides, said sides having cylindrical edges, resilient splices secured tosaid web for joining the said units together.

8. In metal sheet-piling, the combination of units each having a web andsides, said sides having resilient curved edges, means secured to saidweb 'for receiving and holding the said edges.

9. In metal sheet-piling, the combination of units each having a web andsides, said sides having cylindrical extensions, resilient splicessecured to said web for receiving and holding the said extensions.

10. In metal sheet-piling, the combination of units each having a weband sides, said sides having resilient cylindrical extensions, splicessecured to said web having edges fitting over the said extensions.

1 1. In metal sheet-piling, the combination of units each having a weband sides, said sides having resilient curved edges, splices secured tosaid web having elastic extensions for receiving and compressing thesaid curved edges.

12. In metal sheet-piling, the combination of units each having a weband sides, said IIO sides having curved edges, splices secured to saidunits and formed of strips having elastic locking extensions which iitover the said curved edges.

13. In metal sheet-piling, the combination of units each having a Weband sides, said sides having resilient cylindrical edges and arranged sothat the sides of contiguous units overlap each other, ineans `forsecuring the said unitstogether.

14. In metal sheet-piling, the combination of units each having a Weband sides, said sides having Cylindrical extensions and arranged so thatthe sides of contiguous units overlap each other, resilient meanssecured to said Web for locking the said units.

15. In Inetal sheet-piling, the combination of trough-shaped unitshaving coinpressible edges and arranged so that the sides of contiguousunits overlap each other across their entire Width, resilient nieans forlocking the said units together.

16. In metal sheet-piling, the combination of trough-shaped units Withsplines forni ed oi ilat strips having elastic edges.

17. In metal sheet-piling, the combination of trough-shaped units havingelastic edges and splices each 'formed oi a Ilat strip having upturnedelastic edges.

18. In nietal sheet-piling, the combination of units each having a weband sides, said sides having coinpi'essihlc edges, splices sccured tosaid units and each 'formed of a llat strip having upturned curvededges.

In testimony whereof I ailix my signature in presence of two witnesses.
